Show 1990 AFRC Int'l Symposium time basis, average inlet gas flow rates were equal, and average inlet concentrations of NO were approx. 1000 ppmv. Scrubber temperatures for the data included in Figures #5-10 are at ambient temperatures, although analyses were done at both higher and lower temperatures. Figure #5 shows the results of experimentation using a water scrubbing system with an inlet C12:NO molar ratio of 2.5. The point at which the chlorine has been absorbed and the hydrolysis has started results in a noticeable drop in solution pH, due to HCl formation.
